Impossible to know up front. I think one issue you'd run across when doing something like that it that Node is not an application in the sense that Redis is an application. It's mostly a JIT-compiler for applications that are written in Javascript. Porting a Node application to run on Arrakis would probably involve changes to both Node and the Javascript application code, particularly if you want to run close to the hardware performance limits. That's doable, but I doubt you could preserve the APIs that Node currently exposes to applications. (The FS module would be especially problematic!) What could be useful is to ditch Node's existing IO APIs and provide bindings to the Arrakis IO library directly.
